       Service-Oriented Architecture (SOA) is a promising paradigm for
       developing distributed systems. It offers flexibility, dynamism
       and interoperability. Robustness is the dependability attribute
       which  measures the degree to which a system operates correctly
       even  in  the presence of stressful environmental conditions or
       exceptional  inputs,  such as faults. Web Services are the main
       technology  for  implementing  SOAs.  Since  Web  Services  are 
       usually  deployed  on the internet – an unstable environment –,
       robustness  problems  might arise if the system is not properly
       tested.  These  problems might cause unexpected system behavior
       and  must  be  avoided. On this context, we present WSInject, a
       fault  injection  tool  for  testing  single  and  composed Web
       Services,  which  enables  the user to evaluate the behavior of
       Web  Services  in  the presence of faults. It is able to inject
       both  communication and interface faults and was designed to be
       the  minimally  intrusive.  This  report  describes  WSInject's 
       design and architecture, explains how to use it, compares it to
       similar  tools  and  presents  our preliminary experiments on a
       simple system.
